Tozczll @climalit concemfwx i `213eitlinovvnthat I, CLEMENT S'riiiiNiiR,

a; citizen of theiUnited Statesfresiding at `Allentown, in the countyof Lehigh and AStateof Pennsylvania, have invented certain i new and useful` Improvements in `Windmill Control for Electrical Equipments, 1 oflivhioh the following is a specification.

My invention has relation topa turbine type orf iif'indmillStorming the subject-matter `of ri-"separate `application for United States Letters Patent, filed by ine under date of apra isai, i).` `i913, sei-iai No; 761,888,

the bed-plate a?, 'and top-plate o4, respectively, are arranged ball-bearings a5 and a,

engaging a vertical sleeve al, in `ivhich, is placedfa 'shaft at This sleeve 'extends beyond the bed-plate nl, and carries in an ineasement b, a dynamo B, having its arma- .,turel, directly applied to the said sleeve androtating therewith; The brushes?)2 and lis, therefor, being located adjacent to said i armature and suspendedfrom the underside up, Q

l and 5: Surrounding the rotor (Z, and outside thereof, are arranged a series of"`sliut ters or blinds e, pivoted to the top-plate a4, and the `bed-plate al. `The series oshiitters or blinds e, is pivotally connected lby tivo sets ofcoiinecting rods e* ande, with the topand bottom dislisfor plates elm and e2,

and are `held together by ineansofvertical connectingwroddto form as itfivere,1`acage e3, Within which the said rotor el, revolves in the "respective ball-bearingslafand a6. ernorcarried by the main driven member of the mill under variable Wind currents, to

The upperpartl of the sleeve a7, is slotted at x12 and als, as illiistiatedin Fig-.4, and

said slots is attached a cened Weighted arms f1 and f2. These `arms by` links f3 and f4, are connected with "a sleeve f5, which latter is fixed to. the shaft as and revolves with the said sleeve. y The shutters or blinds e, are automatically regulated as to their movements under vari able Wind currents in the manner hereafter and this top-plate at, is carried by a series` of vertical supports a2, the latter also carrying the roof a3. The said sleeve a7, also carries below the cams f7, a rack f, with which mesh the ratcheted surface portion f1", of each of the cams f7. Each of these cams f", is provided with a notch fn, as clearly illustrated in Fig. 3, for a depending pin am, of the upper disk or plate el, to engage and to be actuated by said cams in the rack f?, when the shutters or blinds e, are operated by wind currents. The disk or plate el, is provided with an enlarged opening a, in portions as clearly shown in Fig. 3, for the depending cam-rods f6, to travel in the rotary movements of the disks or plates el and e2, to thus, by the opening or closing `of said shutters or blinds regulate 'the speed of the sleeve a7, of the mill, under the control of the governor 7, as well as the dynamov armature 1, rotated thereby'. Unless the speed of the windmill can be positively regulated its use `for operating an electrical distribution system would be unreliable because the mill must develop not only suificient power for such vpurpose but be able to maintain the samesubstantially uniform at all times to full requirements.

`By my invention it has been found in practice to be so, under the described automatic' control of the shutters or blinds by the centrifugal governor-as applied and operating in Figs. 1,3 and 4;

'Having'thus described the nature and objects of my invention, what I claiinas new and'desire to secure by Letters Patent is l. A wind power controlling means, comprising a turbine type of rotor carried on a sleeve rotatable therewith, shutters or blinds movableindependently of said rotor, a gov. ernor operatively connected with said sleeve and with a slotted cam and pin device and the latter in connection witha disk or plate in positive movable` connection with said shutters or blinds, to automatically regulate movement of Vsaid shutters or blinds under variable wind conditions controlled by said governor, substantially as and for the purposes described. V

2. A wind power controlling means, comprising aturbine type of rotor carried by a sleeve rotatable therewith, shutters or blinds pivotally supported in connection with a rotatablel disk independent ofthe action of connection with a shaft located within said sleeve and actuated thereby, a rack and notched cams suspended from means connected with said shaft and having devices toengage the notches of said cams to actuate `the same inregulating under variable wind conditions by means of said governor said lrotatable sleeve, substantially as and for the Ysaid rotor, a centrifugal governor in fixed and pin means actuated by the disk of said shutters or blinds to regulate by means of said governork the speed of said sleeve, substantially as and forthe purposes described.

4. A wind power. controllingmeans having a rotatable sleeve, a turbine type of rotor carried thereby, pivoted shutters or blinds automatically controlled by means operable independentlyof said rotor, a gov* ernor connected with said sleeve and fixed to a shaft movable withinsaid sleeve, and a rack and cam and pin means controlled by said shutters or blinds to regulate by means of said governor the speed of said sleeve substantially as and for the purposes described.

'In witness whereof, I have hereunto set my signa-ture in thepresence of the two subscribing witnesses.
